Abstract: The present invention relates to a method for moving a two-legged exoskeleton (1) receiving a human operator, the method comprising the implementation, by data processing means (11c) of the exoskeleton (1), of steps of: (a) obtaining a theoretical basic trajectory of the exoskeleton (1) corresponding to one step; (b) setting the parameters of the theoretical basic trajectory based on a single parameter so as to define the theoretical basic trajectory of the exoskeleton (1) as a virtual guide with a single degree of freedom; (c) in response to forced movements of the exoskeleton (1) made by the human operator, operating a controller defining the progression from an actual position of the exoskeleton (1) based on said single parameter by stimulating a spring-damper link between the exoskeleton (1) and the virtual guide so as to implement an actual basic trajectory close to the theoretical basic trajectory.

Abstract: An attachment system for securing an accessory (e.g. a bumper) to a vehicle (e.g. an all-terrain vehicle) is disclosed. The attachment system generally comprises at least one locking mechanism mounted to, or integral with, the accessory, and at least one receiving member, mounted to, on integral with, the vehicle. The locking mechanism generally comprises an actuator configured to actuate or displace at least one locking arm between an inoperative (or unlocked) position and an operative (or locked) position. The receiving member generally comprises at least one opening configured to receive therein at least a portion of the locking mechanism. The attachment system generally allows the installation and removal of the accessory by actuating the actuator of the at least one locking mechanism.
